The 17E165715 is a shielded Metal Backshell, 17E series, die-cast zinc housing and PVC (UL94V-0) grommet, A-size shell (15 standard or 26 high density contacts). The metal backshell accommodates most standard and high-density D-subminiature connectors and is appropriate for cable assemblies requiring compliance to FCC 20780. This version is highly durable and provides EMI/RFI protection. The rubber grommet compression insert forces the cable’s shielding against the inside of the cable exit area, assuring shielding.
